Early Android adopters who picked up the G1/HTC Dream might be feeling the pinch of scarce system memory in the near future. The Android and Me site details the G1's lack of space for post-Cupcake updates (and put it in stark chart form), along with pointing to a not-quite-optimistic tweet from an Android engineer. T-Mobile responded that it's "working with Google to introduce future software updates" to the G1, but it's hard to imagine anything less than a feat of software magic keeping G1 owners from being really inconvenienced by a total re-install, or simply not getting any more upgrades.
